7b003b24ea Refactored DatabasePager and related classes to introduce support for 
multi-threaded paging, where the Pager manages threads of reading local
and http files via seperate threads.  This makes it possible to smoothly
browse large databases where parts of the data are locally cached while
others are on a remote server.  Previously with this type of dataset 
the pager would stall all paging while http requests were being served,
even when parts of the models are still loadable virtue of being in the 
local cache.

Also as part of the refactoring the DatabaseRequest are now stored in the
ProxyNode/PagedLOD nodes to facilitate quite updating in the cull traversal,
with the new code avoiding mutex locks and searches.  Previous on big 
databases the overhead involved in make database requests could accumulate
to a point where it'd cause the cull traversal to break frame.  The overhead
now is negligable.

Finally OSG_FILE_CACHE support has been moved from the curl plugin into
the DatabasePager.  Eventually this functionality will be moved out into
osgDB for more general usage.

965c72f5bd From Eric Sokolowski and Robert Osfield, moved command line option usage setup

96f2062115 From Miguel Escriva, "Attached to this mail you will find some files to work with the Philips WOWvx displays. 
It's implemented in the same way that 3D Spherical Display and Panoramic Spherical Display.

You can test it running:
   osgviewer --wowvx-20 cow.osg
   osgviewer --wowvx-42 cow.osg
depending on the size of your Philips WOWvx display (20" or 42")

Other arguments you can use to control the 3D effect are:

--wow-content <value>
   This value defines the kind of content that can be:
      0: No depth
      1: Signage
      2: Movie
      3: CGI
      4: Still

--wow-factor <value>
   Percentage of the display recommended depth value. Default 64, Range [0-255]

--wow-offset <value>
   Amount of range behind the screen. Default 128, Range [0-255]
      0: Range is shifted in the direction of the viewer.
      128: Range is equally divided in front and behind the screen.
      255: Range is shifted away from the viewer.

57e7aa31fa From Brede Johansen, "The attached file updates the framestamp and traversal number of the 
updatevisitor in osgViewer::Viewer.

The bug prevented DOF animations because osgSim::DOFTransform checks
the traversal number before doing any updates."

e5a365afee Added support for an update OperationQueue to Viewer and CompositeViewer to allow asyncrnous adding of operations to be added 
to the view to be done during syncronous updateTraversal().

This feature can be used for doing things like merging subgraphs that have been loaded
in a background thread.
